The following issues were discussed in the classroom session (15/3/10):
Type of Design -
4 Wheels. Harder to setup - Unnecessarily so.
2 Wheels. Unless perfectly balanced it would be likely to drag - this was seen as an unprofessional approach.
3 Wheels. Manouevrable and reasonably easy to construct, if not the most original design.
Tracked. Good manouevrability but complicated to construct and needs specific parts.
Hover craft. Too complicated with a lack of manouevrability.
The group decided to analyse a 3 wheeled design and a tracked design further.
TRACKED - Luke Hildred to investigate available track parts.
3 WHEELED - Excellent control. Favourite of the group.
Sensor Choice -
MAGNETIC - Reed switches (Requires further investigation and testing). The less sensitive switch provided in class isn't up to the task - Duncan Scriven to investigate other options.
INFRA RED - Cheap and effective in the right conditions. Lots of online reviews have recommended that these aren't used so the group have decided to forget using them).
LDR - Cheap and effective with extensive research readily available.
